Never in a million years would Irene Bae have guessed this is where she would end up.

A top student at D.E.B.S Academy, Irene is popular, studious, and well on her way to being set for life as far as a career goes. Her impressive record and skills seem to leave no room for error until the reappearance of famed criminal Seulgi. Irene is surprised since Seulgi disappeared off the face of the Earth several years ago after committing a string of crimes ranging from illegal arms dealing to bank robberies. Seulgi reputation proceeds her, her famed heists known far and wide. The success rate? 100%. When the D.E.B.S (Irene, Wendy, and Yeri) are tasked with doing recon after discovering intel saying Seulgi is meeting with a dangerous assassin, Irene knows this is her chance to really solidify her place in the world of espionage. Irene doesn't, however, yet know that all of her plans are about to get really, really ed up.
